Abstract: 1,259,631. Measuring blood pressure. F. HOFFMANN-LA ROCHE & CO. A.G. 7 Jan., 1969 [11 Jan., 1968], No. 921/69. Heading A5K. [Also in Division H4] Apparatus 11 for biological investigations comprises a plurality of ultrasonic transducer elements mounted in spaced relation along the longitudinal axis of a flexible support so that the apparatus can conform to the curvature of a body area to which it is applied. In the embodiment shown for detecting, by the Doppler shift of reflected ultrasonic energy, the wall motion of an artery constrictable under pressure provided by a pneumatic blood pressure-measuring cuff 33, transducer elements 14, 16 (acting as transmitters) and 13, 15, 17 (acting as receivers) are embedded in a silicone rubber layer 31 with a nylon material or natural fibre cloth backing. This assembly may be strapped to a body member or may be releasably fastened to cuff 33 by means of a pocket, a snap fastener, or a strip fastener of the hook and pile type. The number of transducer elements in the assembly, and their spacing, may be varied according to the size of the body part to which they are applied, and the elements may be used as transceivers, with range-gating of received signals. The assembly may be used also for sensing foetal heart motion. Transducer details. Each transducer element comprises a surface-silvered wafer of barium titanate, lead zirconate titanate, lithium sulphate or quartz, mounted in and coplanar with an aperture in a metal housing which provides R.F. screening and electrical connection to the active surface of the wafer. Silicone rubber in the housing damps backward radiation of acoustic energy from the wafer. The active surface is resin-bonded to a plastics lens which provides acoustic impedance matching and also gives a transmission/ reception beam which is broad in the plane of Fig. 8 but narrow in an orthogonal plane, whereby the Doppler detection of motion of objects outside a region of interest is avoided. The lens is acoustically coupled to the skin tissue by water or mineral oil.

Abstract: 1296851 Valves BRYAN DONKIN CO Ltd 16 March 1970 [13 Jan 1969] 1824/69 Heading F2V Control of fluid flow between an inlet 2 and an outlet 3 is effected by means of a two-part piston 23, 24 operable, via a piston rod 21 and a bell crank 18, by means of a rotatable hand wheel 15. With the valve in the open position, as shown in the lower half of the drawing, flow between the inlet and outlet takes place through piston ports 26, through ports 5 formed in the piston chamber 7, and through an annulus 4 surrounding the chamber. Appropriate manipulation of the hand wheel causes the piston to move to the left, as seen in the drawing, until piston part 23 abuts a circlip 45. Further operation of the hand wheel results in the terminal portion 39 of piston part 24, moving into an annular recess 30 in piston part 23, and hence in the compression of two sealing rings 42 and 43 carried by the piston and spaced by an element 44, such compression resulting in radial expansion of the rings into sealing contact with the annular wall 6 of chamber 7, as shown in the upper half of the drawing. The two piston parts are sealed relative to one another by an 0-ring 32 and the piston is pressure-balanced through the provision of passage 28, 35. In a modification, (Fig. 2, not shown), 0-ring 32 may be replaced by a resilient sleeve (46) and the sealing rings 42, 43 may be other than circular in section, i.e. trapezoidal. In a still further modification (Fig. 3, not shown), the manual operating mechanism shown in Fig. 1 may be substituted by a pressure operated diaphragm, with the motion of such diaphragm being transmitted to the bell-crank 8.

Abstract: 1328089 Slave cylinders; locking brakes GIRLING Ltd 26 Oct 1970 [30 Oct 1969] 53324/69 Headings F2E and F2F A vehicle brake actuated hydraulically or pneumatically includes locking means comprising an extensible strut assembly which is lockable in extended position to hold the brake applied after the brake actuating pressure has been relieved, wherein the strut assembly comprises a nut part 7 and a screw part 10 having reversible screw threads formed with an axial clearance to allow limited lost motion of the parts 7, 10 in the axial direction the lost motion being taken up in one direction on service brake application and in the opposite direction upon locking of the strut assembly. As shown in Fig. 1 the strut assembly is incorporated in a double ended wheel cylinder of a drum brake, wherein two pistons 4, 5 are actuable to move opposed tappets 2, 3 upon the introduction of hydraulic pressure into a chamber 6. The screw part 10 has an enlarged head 11 which is urged into frictional clutching engagement with the tappet 2 by a compression spring 12, but this clutching engagement is normally resisted by the pressure in a clutch release chamber 14 acting on a domed-head piston 15. The brake is applied in service and parking applications by pressurizing chamber 6 whereupon piston 4 moves tappet 2 directly and piston 5 moves tappet 3 through the nut part 7, thrust race 8 and a stack 9 of prestressed belleville discs: the nut part 7 is keyed against rotation relative to the cylinder body 1 and with the chamber 14 pressurized the screw part 10 spins by reaction with the nut part 7 so that the parts 7, 10 follow up both actuating and return movements of the tappets 2, 3. However to lock the brake for parking, the chamber 14 is relieved of pressure with the shoes applied to cause the clutch 2, 11 to be engaged and the chamber 6 is depressurized whereby the axial clearance of the threads of the parts 7, 10 of the strut assembly is taken up. The belleville discs contract during any subsequent contraction of the drum but do not become fully compressed. The locking means of the invention may also be incorporated in a single ended cylinder of the fixed cylinder type or slidable cylinder type, and may also be included in a pneumatic cylinder of the push type with the extensible strut assembly including a rotatable spindle in screw threaded engagement with a pneumatic piston, the piston acting through belleville washers on to an output plunger and the spindle being normally held off a clutch by pressure in an axially spaced clutch release chamber: or of the pull type with an output rod connected to a pneumatic piston by belleville washers and the piston having a threaded extension upon which a rotatable nut is mounted. Alternatively, the invention may be embodied in a lock unit separate from the wheel cylinder and acting between two shoes or between one shoe and a brake back plate.
